Querying and browsing resources on the Internet

Building a system for the users on the Internet to search interested resources or to provide guided browsing services has formed an important trend as a result of the rapid accumulation of information, the booming development of information system and the increasing requirement of resource sharing. In this paper, we present the Integrated resource Query and guidedBrowsing System (IQBS), which has been implemented at our laboratory, to achieve this goal. The scheme we proposed takes advantage of the strong power of the database system to structure and query data, and greatly promote the qua!ity and performance of searching resources in Internet. In addition, mechanisms are designed to guide the users on the Internet to conveniently browse resources with a reduced traffic cost.
